This invention relates to box-spring mattresses, and objects of the invention are to provide a sanitary and comfortable box-mattress construction which will retain its original shape, especially at the edges, and which can be readily assembled or disassembled, so that pads and covers can be packed and shipped or stored se arately from-the bedspring, and then quic ly assembled in a sim- 1 ple manner for use.

Further objects are to provide for holding the pads securely in place, and supporting the pads at the edges so that the pads will not become flattened and the wadding bunched up and displaced; and to provide a flexible railing construction which will yield without being permanently deformed, when weight is placed on the edge.

Further objects and advantages will become apparent in the following description,

with reference to the accompanying drawings, in which,-

Fig. 1 is a perspective View of a box-spring mattress embodying my invention, the mattress being shown partially opened at the near corner. v

Fig. 2 is a section through the edge of the mattress, taken substantially on the line 22 of Fig. 1.

Fig. 3 is a perspective corner view showing the mattress spring structure.

With the above-mentioned objects of producing a boxed-in mattress construction, with pads on both sides and entirely enclosed around the edges, a bed-spring structure 1 with raised marginal railings 5 is provided. Included within the railings and protected thereby are removable pads 6 and 7, one on each side of the bed-spring; and enclosing the pads and the bed-spring is a removable covering or tick 8.

The bed-spring comprises a plurality of rows of vertically disposed, medially contracted coil springs 10, interconnected at the end coils 11 and 12 by helical Wire coils 13 which extend between the rows and are threaded onto the projecting adjacent portions 14 of the end coils 11 and 12.

The end coils 11 and 12 are closed by wrapping the end 14 of the wire around the adjacent portion of the coil, and in the outer sides of the end coils of the springs, along the edges of the mattress, are formed straight portions 15, joined to the round part of the coil by the angularly extending portions 16 and 17.

To said end coils are secured up-standing loops 18, the ends of the sides or legs 19 and 20 of which are attached to the end coil portions 16 and 17, respectively. The legs 19 and 20 extend outwardly, in angular relation, and are then bent inwardly to provide horizontal supporting or base portions 21 and 22 in alignment with the straight sections 15 of the coils of the springs, and spaced at either side thereof. The sides 19 of the loops then continue upwardly in the vertical, parallel sections 23 and 24, which join into the elevated horizontal portions or tops 25, which extend in parallel alignment with the proj ecting sections 15 of said end coils.

The helical Wire coil 30 is threaded on to the wire portions 21, 15 and 22 along the edges of the bed-spring, and a second wire coil 31 is threaded through the tops 25 of the loops. This forms a raised marginal railing around the flat sides of the bed-spring, and the railing is flexible to weight placed on the edges of the mattress, but is not easily permanently deformed.

The pads 6 and 7 are confined within the marginal railings, and at the edges of the pads are provided the flaps 33, which start at the upper side of each pad, are wrapped around the railing'and buttoned, as by snapfasteners 34, to the under side of the pad, between the coils of the springs. In this manner the edges of the pads are held snugly against the railing, and the pads will not become flattened out at the edges.

The pads and bed-spring are then completely enclosed by the cover 8. The cover is divided into two halves in the mid portion of the three adjacent edges of the mattress, and. the halves are buttoned to the flaps of the pads'by the fasteners 35. The cover is then closed by the slide 36, which causes the interlocking rows of hooks 37 and 38 to become engaged.

The parts can be readily assembled, so

that they can be shipped from the factory with each part separate, saving expense in storage and transportation, and enabling easy removal for cleaning or replacement.

5 While I have described but one illustrative embodiment of my inventon, many departures may be made from the exact construction shown within the spirit of the invention, as defined in the following claims:

1. In a mattress, a plurality of rows of vertically disposed interconnected coil springs, the springs at the edges having closed end coils with straight portions at the outer sides,

a helical wire rail threaded on to said straight portions, upstanding wire loops havin g vertical portions in the sides of the loops connected to said rail and inwardly projecting end portions attached to the end coil of the adjacent spring, and a helical wire rail threaded on to the upper portions of the loops.

2. In a mattress, a plurality of rows of vertically disposed interconnected coil springs, the springs at the edges having closed end coils with straight portions at the outer sides, a helical coiled wire rail threaded. on to said straight portions, upstanding wire loops having their ends attached to the end coils of the springs, the loops having :0 straight base portions threaded into the rail at each side of said straight portions of the springs, and a coiled wire rail threaded t roughthe upper portions of the loops,
